BICYCLE.

SPECIFICATION forming part of Letter-re Patent 55o. 337,774, dated March 9, 1886. Application tiled February l, 18 3.); I Serial Xo. l 55,1l30. (No moel.)

The following is adescription of what I con sider the best means of carrying out the invention.

The accompanying drawings form a part of this specification.

Figure l is a general side elevation of a bicycle made according to my invention. (The remaining figures are on a larger scale.) Fig.

2 is a cross-section through one of the spokes. Fig. 3 is a cross-section through one leg of the fork. Fig. 4 is a cross-section through the rim. Fi s. 5 and 6 are modifications. are cross-sections corresponding to Fig. 2.

Similar letters of reference indicate corresponding parts in all the figures where they occur.

The drawings represent the novel parts with so much of the ordinary parts as is necessary to indicate their relations thereto.

Parts not represented or described may be made in the ordinary manner or in any suitable manner.

A is the shaft, which may have the usual cranks for impelling it by the feet applied either directly or through treadles arranged to act leverwise through suitable links. All these parts, as also the bearings, provided or not with anti-friction rollers or balls, may be as usual, except as hereinafter set forth.

B is the hub of the wheel.

C- C, 8m, are nicely made and bent pieces of steel, which perform important functions. Both ends of each piece 0 is received in the hub B and secured therein. Each extends outward to the periphery of the wheel, then extends along the periphery, and then extends inward. Thus each forms a portion or the a small wheel, is ready to try a larger one, he too They.

whole of the rim between two arms and aportiou or the whole of two arms. I have shown the arms as curved. This may be of advantage in giving elasticity.

In what 1 (sto m the most complete form of the invention each piece 0 constitutes one-half oteach arm. Two adjacent pieces, 0, are applied together and firmly brazed to form an arm. An additional piece, D, extends quite brazed to the curved portions of the several pieces 0. Each piece 0 is in section half ofa hollow cylinder. Two apply together edge to edge to constitutea spoke or arm of the wheel. In the rim the piece 0 applies to the exterior piece or continuous ring, D, so that the entire outer face of the are formed by G and the entire inner face of the corresponding part of D are in contact. They are brazed together over the whole surface, making a very strong and stiff rim,suitable to receive a rubber tire. The part D is concave or hollowed on its exterior. lt may be of metal, similar, originally, to G. The wheel is of great strength, yet narrow and light. Unlike the wheels in common use with wire arms, every part is capable of serving both to resist a thrusting and a tensile force.

E is a rubber tire matching into the hollow exterior of the rim D. It is a hollow tube, and may be in all respects similar to the vulcanized rubber employed for hydraulic hose, except that its ends are smoothly joined to form a continuous hollow rin The l'ork which carries the bearings and, by swiveling in the main frame, guides the vehiole is extensible. The lower part of the fork is ifiarked M. Each leg at this point is hollow and of oval section. The upper part, N, of each fork is solid, or is a smaller hollow part or tube of corresponding section. The upper parts slip adj ustably up and down in the lower part, being held in the required positions by pinching-screws 0. These screws are set on the front or rear side of each leg of the frame, so as to be out of the way.

The main frame is correspondingly made adjustable, the upper part, Q, matching within .the lower part, 1, and secured by a pinchingscrew, B. When the rider, having learned on around. the periphery of the wheel, and is lengthens the fork by shifting N upward in M and confining it anew by the screw 0, and also by shifting the part Q upward in P and con fining it anew by the screw R. I

F is the ordinary small wheel, carried in the part 1?, which performs its usual functions.

The construction of the wheel described will be made subject-matter for a separate application.

Modifications may be made in the formsand.

consider either of these features essential to the success or partial success of the invention.

l l I can make a good wheel with straight arms l l l extending directly radial.

The wheel may be used for other light car- I p rel'e r This contributes to the I do n'ot riages-as tricycles, buggies, band-carts, childrens carriages, wheelbarrows, 820.

For very light wheels only the alternate pieces 0 may be used. This will leave each spoke or arm of the wheel composed of only one part C.

I claim as my invention- 1. A bicycleframe having its standards made in sections, the parts N N Q operating within sleeved parts M M P and a djustably secured therein by set-screws, as O R, as and for the purposes set forth.

2. The bicycle described, having extensible arms Til N and confining means 0, in combination with extensible frame P Q, and confining means l t-,and with a wheel, B O, and adapted to allow the said wheel to be replaced by i one of a different size, as herein specified.

l in testimony whereof I have hereunto set 1 my hand, at Hartford, Connecticut, this 27th 6 day of December, 1884., in the presence of two subscribing witnesses.

G. S. LONG.
